Siemens SENTRON 3VA MCCB – Thermal Magnetic Trip Unit –
3VA1463-4GE42-0AA0
The Siemens 3VA1463-4GE42-0AA0 is a SENTRON 3VA1
series molded case circuit breaker (MCCB) designed for reliable
protection of low-voltage power distribution systems against overload
and short-circuit faults. It is widely used in industrial switchboards,
PCC/MCC panels, feeder and incomer circuits, OEM machinery, and infrastructure
electrical systems where high current capacity and strong fault
interruption are required.
This model belongs to the 3VA14 frame series (up to 630A
class) and is equipped with a thermal magnetic trip unit (TM220 / ATFM
type). It provides adjustable overload protection and fixed magnetic
short-circuit protection, ensuring stable coordination and reliable system
safety in industrial power networks.
It is a 3-pole MCCB with 630A rated current and 36kA breaking
capacity at 415V AC, making it suitable for heavy-duty feeder and
incomer applications in LT distribution systems.
